ATOIVIIZER.

SPECIFICATION forming part of Letters Patent No. 456,205, dated July 21,1891.

Application iiled May 4, 1891. Serial No. 391,496. (No model.)

To all whom it may concern:

Be it known that I, HENRY RoBINsoN,a citizen of the United States,residing at Vaco, in the county of McLennan and Statev of Texas, haveinvented certain new and useful Improvementsin Atomizers; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters and gures ofreferenceqmarked thereon.

This invention relates to certain new `and useful improvements inatomizers or instruments for distributing powders or'liquids;A

and it has for its objects, among others, to provide an improved deviceof this character having provision for closing the exit-passage andpreserve the strength of the medicated powders or fiuid and permit ofthe carrying of the same within the body of the device without danger ofspilling. By detaching the bulb it is used as a powder-box or a bottlefor fluid.

Other objects and advantages of the invention will hereinafter appear,and the novel features thereof will be specifically defined by theappended claims.

The invention is clearly illustrated in the i accompanying drawings,which, with the letters of reference marked thereon,form a part of thisspecification, and in which- Figure l is a longitudinal central sectionthrough my improved atolnizer, with a portion of the bulb broken away.Fig. 2 is a longitudinal section of the outer tube removed, with theupper portion of the box or body of the device shown in position thereonby dotted lines. Fig. 3 is a similar section through the inner tube andits plug, with the other half of the box or body of the device shown inposition thereon in dotted lines. Fig. et is a cross-section on thelinezz of Fig.l. p Like letters of reference indicate like part-s throughoutthe several views.

Referring now to the details of the drawings by letter, A designates thelower portion of the body or box, which may be of any suitable materialand size, and provided at one end with an interiorly-threaded neck d,and at the other end tapered from the inside outward, as shown at h, toform a tight joint with the correspondingly-formed end of the otherportion of the body or box, as shown,

'the other portion B being formed with an interiorlyfthreaded neck c, asshown.

C is a tube havingone end screw-threaded, as shown at d, and engagedwith the threads of the neck of the lower portion of the body,

the tube being extended beyond the said portion and designed to 'bedetachably engaged with a rubber bulb D, as shown in Fig. 1.

This tube is provided with a plug E, which is. fitted therein near itsupper end, and above this plug the tube is provided with an opening eupon one side, as shown in Figs. l and '3, and below the plug with aside opening f,

and adjacent to the latter opening a valveseat gisformed in the saidtube, as seen in Figs. l and 3. rlhe lower 4end of the plug is at such adistance above the valve-seat as to permit the upward movement of thevalve and disclosethe side opening in the tube.

`F is a tube secured in the neck 'c of the portion B, and G is thedischarge tube or nipple detachably held in the said neck c, as shown inFigs. 1 and 2, and it is provided with a suitable discharge-opening h,as seen in Fig. 1. The tube F is provided at a point opposite theopening c in the tube C with a like opening 'i and at a point oppositethe opening f with a like opening j, which communicates with adownwardly-extending short tube H open at its lower end, as shown inFigs. 1 and 3.

Y I is a ball arranged in the tube C and normally seated on thevalve-seat g, and closes the passage upward through the tube C, asshown.

The operation will be readily understood.

The box is lled with the powder or liquid and the upper portion with itstube turned round so that the openings in the two tubes l will becoincident, as shown in Fig. 1, the ball being seated on its seat. Bypressing the rubber bulb the air will be forced in through the innertube and the ball forced from its seat and the air forced down the shorttube and into the powder, forcing the same-out through the openings eand c' into the discharge-tube and out. As soon as the pressure on thebulb is relaxed the ball seats itself and closes the passage through thetube. By turning the upper portion with its tube a loo quauterwvayvround, or more, the openings in the two tubes will be brought otherwisethan coincident, and the communication between the body of the deviceand the dischargepipe closed.

Suitable 1narks or a stop inside the instrument should be provided uponthe two por tions of the body to designate the relative positions of thetwo tubes, so that one can readily tell how far to turn the upperportion to have the holes register.

In Fig. 4 I have shown the position the parts assume when the device isclosed.

It will be readily seen how the powder or fluid is kept in the boX orbody of the device and prevented from losing its strength when not inuse. The parts are readily detachable for the purpose of cleaning` orfilling the box.

J is a flexible tube placed through the top of the box land oi' suicientlength to reach to the bottom thereof, and when in use with the rubberbulb the air forces the fluid from the bottom of the box through thetube. When the instrument is used for a powder-blower the flexible tubeis removed. The tube is provided with a hard-rubber tip J', and withinthe inner tube at the bottom of the box is a plugj for the attachment ofthe rubber bulb.

XVhat I claim as new is- 1. The combination, with the two-part body, ofthe tube carried by one part and provided with side openings, the tubecarried by the other part and provided with corresponding openings, oneof the tubes being rotatable on the other, and a valve arranged in theinner tube, substantially as specified.

2. The atomizer described, consisting of the two-part body, each partprovided with a screw-threaded neck, the inner tube held in one neck andprovided with side openings and plug between them, a ball-valve in thesaid tube, a rubber bulb connected therewith, and the outer tube carriedby the neck of the other part of the body and rotatable and providedwith side openings and sleeved on the inner tube, substantially as andfor the purpose specified.

In testimony that I claim the above I have hereunto subscribed my namein theprescnce of two witnesses.

HENRY ROBNSON.
